There are no 'performance' oriented suspension kits for the Ranger, but they do pretty well with some sensible upgrades. The lowering kits aren't bad, but they might lower the truck more than you're wanting to. The basic rules for handling can be applied to Rangers just like any other vehicle though.
1. Lower the center of gravity- this is done by dropping the height of the truck, the lower you go, the more your CoG drops. Don't drop it so far that the suspension can't cycle though.
2. Reduce body roll- sway bars are a great place to start. Most Rangers only had a front sway bar, so adding a rear bar is a big gain. There are options for thicker bars from other models or aftermarket as well.
3. Increase grip/traction- sticky rubber goes a long way. Getting lower profile tires, or wider tires are both good options as well. rangers can fit some really wide tires both front and rear, so this is an area with great potential. Just remember that you get what you pay for.
4. Custom setups with 4 links, irs, or front clip swaps would be the final and most extreme end of the spectrum.
